The Optometric Manpower Resources Project, funded under government contract since June of 1971, has completed its 1973 national census of licensed optometric manpower in the United States. The first article in this series of three reported on the distribution of optometrists by census region and the current ratio of practicing optometrists to civilian population. This second article reports on the principal forms of employment of active optometrists, the distribution of number of years in practice and practice size. The data indicate that there has been a shift away from self-employment (88% in 1968, 77% in 1973) into more varied forms of salaried employment, especially among those in practice fewer than ten years. Practice size is shown to peak at between fifteen and twenty-four years in practice with a median of approximately 5,400 patients.
验光人力资源项目自1971年6月起由政府合同资助，现已完成其对美国持证验光人员的1973年全国普查。本系列三篇文章中的第一篇报道了验光师按普查区域的分布情况以及执业验光师与平民人口的当前比例。第二篇文章报道了在职验光师的主要就业形式、执业年限分布和诊所规模。数据表明，就业形式已从个体经营（1968年为88%，1973年为77%）转向更多样化的受薪就业形式，尤其是在执业年限少于十年的人群中。诊所规模显示在执业15至24年之间达到峰值，中位数约为5400名患者。
